Question

The slopes of perpendicular line segments are start fraction one over three end fraction and start fraction d over five end fraction. What is the value of d?

Answer 1

d = -15

Explanation:

The slopes of perpendicular lines have a product of -1.

1/3·d/5 = -1

d/15 = -1 . . . . simplify

d = -15 . . . . . multiply by 15
